SSHD Key Generation Notes
-------------------------

 1. Install openssh on your local machine

 2. Run ssh-keygen -t rsa -f [filename] -N '' -C ''

 3. Open a browser to the Linksys box (default 192.168.1.1)

 4. Open [filename] and copy contents to Linksys web interface field
    "RSA Host Key in ASCII Armored Format".

    This is the linksys sshd daemon's private key.

 5. Copy your public key from /[user name]/.ssh/id_rsa.pub to the 
    "Authorized Keys" field.

 6. Enable SSHD in the web interface

 7. Enter your Linksys password twice at the top of the screen

 8. Click on "Save Settings"

 9. Restart your Linksys box


Client Mode Notes
-----------------

Client mode is set on the Basic Wireless Settings web page. When in client
mode your WRT54G will try and associate with an AP every 30 seconds.

If you leave the Linksys in it's normal mode of operation, the wireless and
the 4-port LAN interfaces share a common IP address. You will have to set the
WAN/Internet port to an IP address in the same sub-network and set the WAN
gateway address to the address of the AP you want to reach.

Example:

Internet Connection
 Address:		192.168.1.2
Netmask:		255.255.255.0
Gateway:		192.168.1.3   ** must be the address of the AP

Router IP Address:	192.168.1.1
Router Netmask:		255.255.255.0

However, if you wish to split the wireless interface from the 4-port LAN
this option is now available in the Setup menu. Enable it by setting WLAN 
IP to Enable. When you hit the submit button you will see input fields for
IP Address, Netmask, and Gateway.

This will allow you to talk to an AP that is on a different sub-net than 
your local LAN.

The separate wLAN address setting makes a couple of assumptions -

1) If you are in "client mode" the 4-port local LAN interface will be 
   bonded/forwarded to the wireless LAN interface (using iptables).

2) If you are in "AP mode" the WAN/Internet interface will be bonded to 
   the wireless LAN interface (also using iptables).

The reasons for these assumptions are that if you are running client mode, 
you are most likely trying to move data from your local LAN devices to a
wireless network that has an Internet connection.

But if you are running the device as an AP, you are most likely connecting
it directly to an Internet connection via the WAN/Internet port. You also
probably want to be able to use the web based firewall rules, which only
work for this port.

Examples:

	Client mode

	Wireless LAN IP:	10.0.0.1
	Wireless Netmask:	255.255.0.0
	Wireless Gateway:	10.0.0.2 <-- the AP's address you are connecting to

	Local LAN IP:		192.168.1.1
	Local Net Mask:		255.255.255.0

	Ap Mode

	Wireless LAN IP:	10.0.0.2
	Wireless Netmask:	255.255.0.0

	WAN/Internet IP		192.168.1.1
	WAN Netmask:		255.255.255.0
	WAN Gateway:		192.168.1.8  (or whatever your ISP says)

	* note: you can also probably run DHCP for the WAN interface but
		this is untested
